EAST RUTHERFORD, N.J. — The New York Giants started rebuilding their offensive line and found a little security at running back on the opening day of free agency in the NFL.

The Giants reached agreements with former Kansas City guard Geoff Schwartz and Oakland running back Rashad Jennings on Tuesday, the players announced in tweets. Seattle Seahawks linebacker O’Brien Schofield also agreed to a two-year, $8 million deal.

All three players were on their way to New Jersey to sign the deals.

A person close to the negotiations also said the Giants re-signed four players from last year’s team. The person, who requested anonymity because they team had not announced the re-signings, said placekicker Josh Brown, cornerback Trumaine McBride, safety Stevie Brown and running back Peyton Hillis will be back next season.
